they paid a lot more then 50k for a truck up fitted like that. yah 2wd sucks but with weight in the bed you'll be fine...with that setup you should try and sub for your town plowing or sub for a guy with some large commercial lots, you should be able to pull in between $100-120 an hour with the salter and 10' plow.

the chevys didnt offer 4x4 in their HD 3500s until I believe 02/03??

They didnt offer it factory but monroe makes a 4x4 conversion for them. If you have the $$ thats one badass truck!
